Rickettsial pox

Rickettsial pox is a disease spread by a mite. It causes a chickenpox-like rash on the body.

Causes:

Rickettsial pox is caused by the bacteria, Rickettsia akari. It is commonly found in the United States in New York City and other city areas. It also has been seen in South Africa, Korea, and Russia.

The bacteria are spread by the bite of a mite that lives on mice.

Symptoms:

The disease begins at the site of the mite bite as a painless, firm, red lump (nodule ). The nodule develops into a fluid-filled blister that bursts and crusts over. This lump may be up to an inch wide.
